(57) A memory positioning system for use in a remote control rear-view mirror having electric
motors for adjusting the mirror's position, which position is electrically detected
by linear potentiometers connected to a microprocessor that records the potentiometer-generated
signals. After the signals corresponding to a pre-selected position have been recorded
and the mirror adjusted to a different position, the mirror can be returned to the
pre-selected position by commanding the mircroprocessor to operate the motors until
the potentiometers detect the previously recorded positions corresponding to the recorded
signals. A rib and slot on the mirror's main spherical pivot mounting provide only
a limited predetermined amount of vibration-absorbing pivotal movement about an axis
which intersects the plane of the mirror. The mirror also has stops which permit only
a limited amount of pivotal movement about the same axis.
